DEVICE FOR SETTING SAVE? TEE-13H OR THE LIKE.

Application filed October 31, 1927.

lvly invention relates to an improved dcvice :tor setting saw teeth and is adapted to be used on crosscut saws or handsaws.

lit an object oi my invention to provide a saw set which is simple in structure and reliable in operation.

i lnothor object oi my inventioi'i is to provide a saw set which may be used anywhere and. may be operated by one person.

Still. another object oi my invention is to 'n'evide a StlffSUlllClGllll saw set which compris sharp points for insertion into any surface, such as a work bench or a stump or log.

illhe device is provided with a lever having a hammer head which is detachably secured and may be removed for the purpose oi driving the sharp points into the surface d ired. whereupon the lever is again attached to the device, as the lever serves also the purpose of pressing down the saw teeth against the bevel which is provided on. the anvil portion of the saw set.

The saw set also comprises a carriage or support for holding the saw.

(lther objects and advantages will appear tirom the detailed description which follows.

I attain these objects and advantages by the mechanism described in the drawing wherein is shown a perspective view of my improved device for setting saw teeth.

Referring to the drawing, 1 is a substantially T-shhpod bracket having a verticalv arm 2. and a horizontal arm 3 at right angles to each other. The vertical arm is bifurcatcd at its lower end to liorm prongs 4- and 5 which serve a purpose to be hereinafter described. The upper end oi the vertical arm forms an anvil head portion (3 having a bevel "l' aii .t which the saw teeth pressed durthe set-ting operation.

he horizontal arm 3 is provided with openings 8 within which a threaded post 9 is received. By reason of the spaced openings it is possible to vary the distance oi the post 9 from the vertical arm 2. As shown in the drawings the horizontal arm 2 is 'nrovided with winged ends 10 and 11 which serve the purpose of design.

The upper end. of the post 9 is provided with a squared head 12 upon which the saw support may be placed. The saw support comprises the cross piece 13 having slits at each end for receiving the slides 14, 15. The slides may be adjusted as to length by means saw is pushed down.

Serial No. 229,946.

of set screws 16, 17. At the free ends of the slides adjustable uprights 18, 1,9 are providal against which the back of the saw a. A loose cross piece may also be provided. which rests against the uprights 18, .19 to serve as a back support for the saw.

A hand lever 91 is detachably secured to an ear on the vertical arm 2 on the side thereot opposite the. horizontal arm and the same side oi. the bevel above referred to. The hand lever is secured in place by the bolt and-nut 28. The outer end of the hand lever is provided on its under side with an tniarged portion 2% which serves as a hamnier head. i obtuse angle member is secured by one arm 26 to the upper side of said hand lever .21. A boss or punch 27 is provided on the under side of the arm of said obtuse angle member. The boss or punch 27 provided with bevel 28 which is :ulaptcd to coact with the bevel 7 on the anvil. tor setting the saw teeth.

The operation of the described device is as ifollows: The hand lever is first removed from the set and by striking the anvil head portion the vertical arm of the bracket is driven into a stump or log after which the hand lever is replaced. The saw which is to be set is laid across the support with the teeth ei' ending over the bevel. The slides on the )port are set so as to permit the extremities of the teeth to lie exactly across the bevel. [is pointed out above, the support is adjustable in height by reason oi? the threaded post 9 as well as for distance by reason of the slides 14 and 15.

Ajliler the saw arranged so that the teeth are in a proper position, the hand. lever raised and by means oi? the punch or boss provided on the hand lever, the tooth on the The size of the punch is such that only one tooth is at a time. The hand lever is then swung away to release the saw which is shifted forward to present another tooth and the preceding operation is repeated.

It is to be understood that the set may be regulated by lowering the saw support below the plane of the anvil head portion whereupon the teeth are pitched up and a greater set is given to the teeth. If a less set is preferred the saw support is raised above the plane of the anvil head portion. To set a narrow saw the post 9 is moved forward into one 01 the other openings in the horizontal arm. In operation, to prevent any possible recoil, one hand may operate the hand lever While the other hand holds the back of the saw although this is not really necessary.

All that has been said above in the description of my preferred embodiment is oiiered by Way of illustration and not limitation. I do not-wish to be limited to the exact structure of the preferred embodi ment shown and described, or to any particular material used in the construction of parts, or to the design of parts, but desire protection as against any variations in struc ture which utilize the principle of my invention and fall within the purview of my invention and are Within the spirit and scope of the following claims.

The invention having been set forth, What is claimed as new and useful is: i

1. A device for setting saw teeth or the like'comprising in combination a bracket means, said bracket means consisting of a vertical arm and a horizontal arm, said vertical arm having gripping means at one end thereof for attachment to a surface and an anvil head portion at the other end thereof, a saw supporting means for holding the saw teethon the said anvil head portion, said anvil head portion having a bevel thereon to provide the set for the saw teeth, and punching means for pressing said saw teeth against said bevel, said punching means comprising a lever hingedly secured to said vertical arm oppositely of said horizontal arm, said lever having an angle member secured thereto, said angle member having a boss thereon, said boss having a bevel corresponding to the bevel of said anvil head portion and being adapted when raised by the lever arm, to contact the anvil head portion for setting the saw teeth.

2. A device for setting saw teeth or the like comprising in combination a bracket means, said bracket means consisting of a vertical arm and a horizontal arm, said vertical arm having gripping means at one end thereof for attachment to a surface and an anvil head portion at the other end thereof, a saw supporting means for holding the saw teeth on the said anvil head portion, said anvil head portion having a bevel thereon to provide the set for the saw teeth. and punching means for pressing said saw teeth against said bevel, said saw supporting means comprising a post secured to said horizontal arm, a cross member attached to said post at right angles thereto, said cross member having slide members at the ends thereof for holding the saw, said posts being adapted for adjusting the height of said supporting means above said horizontal arm, and said slide members being adapted for adjusting the distance of the saw from said vertical arm and for holding the saw tooth in position againstsaid anvil head portion during the setting operation.
